SPECIFICATION forming part of LettersPatent No. 270,294, dated January9, 183.

Application filed March 20, 1882. (No model.)

.To all whom z't may concern i Be it known that I, SIGMUND FEUsT, of thecity, county, and State of New York, have invented certain new andusefulImprovements 5 in Bufflng and Polishing Machines, of which thefollowing is aspecilication.

The object of this invention is to furnish a bnfing and polishingmachine for articles of brass or other metal, which is easily and safelyro worked and constructed in such a manner that `the shaft carrying thebuffing'material can be adjusted in downward direction as the materialwears off, and in which the heads which retain the buffing material canbe conveniently removed and reduced in size Without taking the bufiingmaterial from the shaft.

My invention consists in the combination, with the buffng-wheel and theshaft-carrying the same', ot' separable heads,lwhich can be detachedrfrom the' shaft and reduced so as to correspond to the size of thebufling material as it wears oll without 'removing the latter from theshaft, the bufiing material being divided by intermediate disks into anumber of z5 separate sections, all as hereinafter described andclaimed.-

In the accompanying drawings, Figure '1 represents a side elevation ofmy improved buffing and polishing machine. Fig. 2 is a plan with a partbroken o. Fig. 3 is a vertical transverse Section; Fig. 4, a verticallongitudinal section; Fig. 5, a top View of-the mechanism forimpartinglateral motion to the feed-table; and Figs. 6, 7, 8, 9, 10, and 11 aredetails.

Similar letters of reference indicate correepondigg parts.

Referring to the drawings, A represents the supporting-frame of myimproved buing and polishing machine, which supports on side standards,A', the bufng-shaft B, that is revolved byv a belt-and-pulleytransmission from a suitable counter-shaft.

Below the buffng material is arranged a 45 feed-table, C, to whichlongitudinal reciprocating motion and,.simultaneously therewith,

lateral motion isimparted. The reciprocating' motion is imparted eitherby hand or power. In the former case the feed-table is turned in 5o onedirection or back by means of a handwheel, a, keyed to a transverseshaft, c'. For

this purpose a pawl, b, has first to be released from a ratchet, b', onthe shaft c' by means of a treadle, d, and connecting-rod d'. The pawl bserves to lock the feed-table into rigid posi- 55. tion, so as toprevent any accidental motion of the same when the same is not in use.

The feed-table G consists of alower section, C', which is provided atthe under side with racks-@that mesh with pinions e' of the drivingshaftc', the section C being guided by means oftapering side rails,f, 011correspondingly grooved Ways, f', of the supportingframe A.

Upon transverse ways tofthe lower section, C', is guided the uppersection, C2, ofthe feedtable, which section receives lateral motion froma wave-wheel, g, the shaft g of which `is rotated by any suitabletransmitting mechanism from the driving-shaft a'. The Wave- 70 Vw heel gengages an anti-friction roller, gofa fixed arm, g3, applied to a frame,g4, which latter is guidi-d in lateral openings of frame A. The frame g4carries upright arms g5., having anti-friction rollersgsattheir upperends, which 75 latter engage parallel rails hat the center and underside ofthe upper section, UZ. Simultaneously with'the forward motion ofthe leedtable, which is imparted by the pinons and racks ofthe lowersection, the upper section is laterally reciproeated by the mechanismdescribed, or any equivalent thereof, so as to eX pose thereby the workapplied to the feed-table to the action of the bnfling wheel or brush Dand prevent it from getting streaky. 8

The Work to be polished is secured to the upper section ofthefeed-tableC in any approved manner. When the feed-table C has arrivedat its extreme position in one direction the motion ofthe driving-shaftis reversed, and there- 9o by the feed-table returned in oppositedirection, so that the goods are passed va second Vtime below thebuffng-wheel, and 'so on alternately. The heffing-wheel D is inclosed bya guard easing. or hood, D', which is provided 95 with a hopper at thetop, through which the buliing compound is slowly supplied to thebufling-wheel or cylinder. `The hoodl DI4 prevents vthe throwing of thedust toward the operator, so as to protect the same. The standroo ardsA', which carry the bearings of the shaft of the hurting-wheel,areadjusted in inclined length of the driving-belt ot' the butting-shaftneed not be changed, even when the buftingshaft has to be lowered orraised, owing to the wear of the buftlng material or the replacing ofnew material. The inclined standards A are slotted and provided withclamp-nuts 4,so

4as to be rigidly secured after the bufting-shal't has been adjusted tothe propel' relative position on theI feed-table C.

The buffing-wheel D is supported'on the bufiing-shatt B by means ot'separable and detachable heads D2,which arescrewed up against thebnt'ling material by a washer, m, and set and jam `nuts m', as shownclearly in Fig.' 7. The separable heads D? are made of sections u, ofquadrantal or semicircular shape, which are screwed to supporting disksor collars n', asshown in Fig. 11; or they are made of interlockingsections n, applied to supportingdisks n', as shown in Figs. 9 and l0,so that by slightly loosening the washer m and unscrewing theconnecting-disks u the sections a of the heads D2 may be separated fromeach other and removed from the shalt, so as to be reduced in size,without removing the bufting material from the shaft. In this manner theheads of the bufng material can always loe kept at a size whichcorresponds exactly to that of the but'ting material, notwithstandingthegrad-- `nal reduction which takes place in the size of the same bywear. By means of intermediate separating-disks, 0', made of metal,thebuflug wheel or brush D is divided into a number of sections, as shownin Fig. 7, which is of certain advantage in the buffing operation.

Thev buiing wheel, drum, or headv may be composed offelt or othersuitable fabric or material, or these wheels may be composed of acombination o t' materials suitably adapted to the purpose. I make noclaim to the material of which the wheels are made, as any of thewell-known buftng materials may be adopted.

The head D2 of Fig. 8 is formed of two semicircular plates, n fn,secured to similar plates, n', which break joints with the joints of theplates n. The head D2 of Figs. 9 and 10 is formed of two angularinterlocking plates, a n, Screwed to a disk, n. The head shown by Fig.10is composed of segment-rings u,screwed to a disk, fn, onthe shaft B. l

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a bufling and polishing machine, thecombination, with the buftingshaft carrying the bufug material, ofseparable and removable heads for retaining the same, and means,substantially as described, for securing the heads to the buttingmaterial, substantially as set forth.

2. In a buffi-ng and polishing machine, a baiting-wheel composed ofmovable and detachable sections, with disks of smaller diamterinterposed at intervals, and heads pressed against the outer sections,all clamped to gether on the shaft,substantially as described. 3. Thecombination of an adjustable buling `wheel or brush, a feed-tablecomposed of a lower reciprocating section, C', an upper lat.

erally-reciprocating section, C2, a laterally-reciprocating frame, g4,provided with upright arms, the rollers on these arms traversing between rails h, tixed to the bottom of the sec- SIGMUND FEUS'I.
